Product Description
SBW, DBW Full Automatic Compensation voltage Stabilizer
Application
DBW, SBW series single & three-phase full automatic compensation voltage stabilizer is designed for stable AC voltage by inducing and absorbing the Western Europe advanced technology.at the same time combined our national condition. When the outside power supply network voltage fluctuates or the load changes to make the voltage undulation, it can automatically maintain the output voltage to be stable. Comparing with other type voltage regulator, this series product has big capacity, high efficiency undistorted waveform, steady regulation voltage and so on the merit,widely suitable load, withstand instantaneous and overload, long-term continuous working, manual/automatic switching, equipped with the over-voltage protection, lacking phase, phase sequence protection and mechanical breakdown automatic protection, as well as small volume, light weight,convenient usage and installment, reliable movement and so on merit, (two kinds of digital display and instrument indication).Widely used in posts and telecommunications, market, elevator, hospital, school, printing,negotiable securities and so on where all need normal voltage situation.

It is composed of three-phase compensation transformer, three-phase regulating trans-former insulating transformer, transmission system, brush contact system, box body and control systemand so on. The three-phase regulating transformer cylindrical winding outline is processed through polishing and removing the insulation, being smooth conductor surface so as to get good contact for electronics brush; The transmission system composes of electric motor and worm gear, chain wheel, chain link. The electronics brush system structure is reasonable and reliable to guarantee the pressure of the brush; The box body is the seal cabinet type with small volume, good radiating,high-lighting position of examination the measuring appliance, accurate instruction.
Principle of work
SBW series voltage regulator is composed of three-phase compensation transformer TB, three-phase voltage regulator TUV voltage examination unit, motor control and transmission system, contact function circuit and protection circuit. Its electrical schematic diagram shown as Figure I.
The primary winding of the regulating transformer TUV connects as Y shape in the out terminal of voltage regulator, the secondary windings connects compensation transformer principle of work, compensation principle of work, shown as FigurellEg: If does not count the impedance drop of compensation transformer, then Figure II: Uao=Uai+Uac
In the formula: Uai voltage regulator A phase input voltage.
Uao i voltage regulator A phase output voltage.
Uac < voltage regulator A phase compensation voltage.
Its principle is: When A phase input voltage Uai increases A Uai, the compensation voltage Uac also correspondingly changes as A Uac also A Uac= A Uai, makes A phase output voltage Uao to maintain invariable, with the same principle B, C also is so. Its constant voltage process is: According to the change of output voltage, sampling, examination and output the signal control motor SM rotation by the voltage examination unit, and has the chain link after the reduction gear to lead the set of brushes on regulating transformer TUV to skid (or roll) so as to adjust the secondary voltage of voltage regulator, change the polarity and the size of the compensation voltage, and then realizes the output voltage auto stable in the constant voltage precision permission scope, thus achieves the purpose of the automatic constant voltage.
